There are now two distinct factions at the Broncos that are causing instability.

White and Broncos chairman Karl Morris believe it is time to enact a succession plan and want to move Bennett on for 2020, but the super coach has supporters on the board in Tony Joseph and Darren Lockyer.

New chairman Morris is not a traditional rugby league man, and isn't intimidated by the Bennett aura. Morris, a heavy-hitter who is executive chairman of $94 billion superannuation giant QSuper, would have no issue pulling the trigger on Bennett.

A powerplay has been brewing at the Broncos for some time.

White and Bennett are strong, ambitious personalities who like to call the shots. While the CEO heads the chain of command at the Broncos, there is a feeling Bennett, Brisbane's only premiership coach, really runs the show.

That will change at season's end when the Broncos board gathers for one of the most significant meetings in the club's 30-year history.

White and Morris are almost certain to part ways with Bennett, whose only hope of salvation is a Broncos premiership this season.

Bennett is determined to coach the Broncos in 2020 at the age of 70 and insists he will not be exceeding his expiry date.

"No one is going to be more honest with themselves than I have got to be," Bennett said.

"I have a huge responsibility as a coach for a whole lot of things within a club. I have never lied to myself, so I am not going to start now. I feel I know how long I can go on for.

"I am not going to stay a year too long. I am going to be like Billy Slater and go out at the top of my game, but it's not now.

"I want to be at the Broncos. I want to continue to coach. Everyone knows that, so let's see where it all goes."
